SATUMA, ARKANSAS, ASSIGNOR OF ONE-HALF TO JAMES J'. BOYETTE, OF SATUMAARKANSASJ Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed March 15, 1911. Serial No. 614,693.

clear, and exact description of the invention,-

such as will enable others skilled in the-art to which it appertains tomake and use the same.

My invention relates to new and useful improvements in plows andmoreparticu-. larly to a device adapted to loosen the earth to form airpassages therein.

The object of my invention isto provide; a device which,-when operated,will form a passage-way in the groundi'n'which air will be drawn so thatthe ground will-be loosened and aerated and moisture retained.

A further object is to provide means whereby the depth to which. thedevice will operate may be regulated.

Other objects and advantages of my i117 vention will be hereinafter madeclearly ap parent and pointed out in the claimsappended hereto. In theaccompanying drawing, I have shown the preferred forms of my invention.In said drawing, Figure 1 is, a perspective view of my improved form of.plow, and, Fig. 2 is a perspective view of a portion of a modified formwhich my invention may take.

Referring to't-he drawin in which simi' lar reference numerals designatecorresponding parts throughout the several views, 1 is the beam of myimproved form of plow which is preferably constructed of wood and maybe, if desired, formed of sheet metal or any other desired suitablematerial.

The forward end of the beam is provided with a clevis 2 of the usual orany preferred form and at its rear end with a pair of up wardly andrearwardly extending handles 3 of the usual construction, by means ofwhich the plow may be guided.

The air passage forming device of my plow consists of an elongatedtapering member 4 which may be of any desired shape in cross section,but which is preferably substantially circular in cross section. Theforward end of the member 4 is tapered forwardly and downwardly so thatsaid member tends to move deeper into the ground. The member 4 is causedto move at a predetermined distance from the surface as hereinafterclearly set forth.

The forward end of the member 4 is provided. I with a plurality ofapertures 5,

tegrally with or secured to a cutting blade 7 WhICh. 1s verticallydisposed and provided at upper'end with a U-shaped member 8,-

theypart'sof 2 "1d U-shapedmember adapted toextend 'on'either side ofthe beam 1 and be "securedltheretoby' means of suitablebolts 9.

. The lo'werends of .the studs or bolts 6 may bflrs'crew threaded toreceive, nuts, or said endsinaybe sw'aged,-to hold the memfber rigidlyconnected to the cutting-blade 7. The member?- is formed of metal whichv is of narrow-width and has its forward edge sharpened so as to easilypass through, the

ground.

' Thev rear portion of the member 4 isprothrough which studs or bolts 6are adapted to -pass. The studs or bolts 6 are formed invided with alongitudinally extending opening 10 therethroug'h, said 'openingflaringoutwardly at the'rear'end of said member, as shown in dotted lines inFig. 1'. The forward end ofs'a-id opening 10 extends.upwardly and a pipe11- is securedtherein, said pipe extending upwardly adjacent the rearedge of the cutting'blade 'i and through the beam 1. 7

The-upper end of the pipe 11 is provided with a forwardly and outwardlyflaring member 12, for a. purpose hereinafter more clearly set forth-The forward end of the beam 1 is provided with a suitable colt/er orcutting disk 13, which is vertically adjustable relative to said beam.The rear end of the beam adjacent the pipe 11 is provided with avertically adjustable roller 14, the periphery of said roller beingconcaved, so that after the cutting bladehas passed through the earth,the concaved surface of the roller 14- will tend to close the openingformed by said blade.

The cutting disk 13 and the roller 14 are set in desired positions andwill thereafter limit the depth to which the plow will work. Owing tothe tendency of the member 4 to work deeper and deeper into the ground,the roller '14. will be held tightly against the surface of the groundand caused to perform its function of closing the furrow made by thecutting blade 7.

When in use, the plow is drawn forwardly and the member 4 will be drawnthrough the ground, leaving an opening therein. As clearly shown in Fig.1, the roller 14 is mounted forwardly of the rear end of said member 4and tends to pack the earth around the rear end of said member, wherebythe passage of said member tends to form a partial vacuum in the rearthereof. As the member 4 passes through the ground, air will be drawnthrough the pipe 11 and member 12. As the plow movesforwardly in use,the flaring member 12 tends to collect the air in front thereof, whichtravels down the pipe 11 and into the channel formedby the member 4.

In Fig. 2 I have shown a member 4 which instead of being circularincross section, is

elliptical in cross section and provided upon,

opposite sides with flange members 15. The

flange members 15 are substantially trian-- gular in cross section andare secured to the member 4 so that the lower surface of said member andflanges is substantially flat. By this construction, a strip of earth ofconsiderable width can be loosened and aerated.

From the foregoing, it will be seen that I have provided a plowconstruction which is adapted to loosen the earth and to conipletelyaerate the same.

It will further 'be seen that the depth to which the plow will operatemay be regulated.

Itwill further be seen that by providing (channels in the earth and byloosening the surface of the ground above said channels,

' the collection of surface water will be prevented.

What I claim as new is:

1. The herein described plow, comprising a beam, a vertically extendingcutting blade secured thereto, a forwardly extending tapering membersecured to the lower end of said cutting blade, and air conducting meanssecured to said tapering member.

2. The herein described low, comprisin a beam, secured thereto, aforwardly tapering member secured to the lower end of said cuttingblade, an adjustable roller pivotally secure adjacent the rear edge ofsaid cutting blade, and means to conduct air to the rear end of saidtapering member.

3. The herein described plow, comprising a beam, a cutting bladeattached thereto and a forwardly tapering member secured to the lowerend of said cutting blade, the rear end of said tapering member havingan opening therein, an upwardly extending pipe secured to said ta eringmember and communicating with sai opening, the upper end of said pipebeing forwardly and outwardly flared.

4. The herein described plow, comprising a beam, a vertically extendingcutting blade secured thereto, a forwardly tapering member secured tothe lower end of said blade, an adjustable cutting disk secured to theforward end of said beam, a roller adapted to travel in rear of saidcutting blade and means to conduct air to the rear end of said taperingmember.

5. The herein described plow, comprising a beam, a vertically extendingcutting blade secured thereto, a forwardly tapering member secured tothe lower end of said blade, a.

roller adapted to travel in rear of said cutting blade for the purposedescr'bed, and means to conduct air to the rear (1 of said taperingmember.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
